I have a 2004 Chrysler 300M with a 3.5. I have replaced battery, coil packs, spark plugs, and cam sensor. However it still won't crank. It spins over and the fuel pump is engaged when you switch it on. What can be the problem? Mechanic checked fuses and says they are all good. Help! I want to get my car going again.

 

Have you checked the crank sensor? Have seen some issues causing no start. Sounds like you need a technician to replace your mochanic.
Diagnose/ Troubleshoot and solve the problem, not just throw parts at it is the way to go.
Any codes to guide you in the process?
Crank Sensor reports motion to the PCM, Cam Sensor reports position so the PCM turns on fuel and spark at the correct time.
What happened, did it shut off while driving or just not start one day?
Timing Belt OK ???
Kind of need more info to help

 

According to what we have seen online so far there is not a crank sensor only a cam shaft sensor. Of course I am no mechanic and the one who was working on it was having to look online as well. The timing belt has not been checked at this point but I do know that you do not hear any knocking when you try to crank it. It shut off going down the road just like I had switched it off which I had not done. It only throws 1 code which is a P0700 I believe which is saying something about the transmission. I am far from knowing how to work on a vehicle except for minor stuff such as battery etc. I just want to get my car going again.

 

The crankshaft sensor is on the passenger side back of the motor and is held in by one small bolt.
I had an 04 Dodge Intrepid which had the same motor in it.
